[0034] The above content will be described more comprehensively below with reference to specific embodiments and accompanying drawings.

[0035] Figures 1-2 A perspective view of an integrated debugging and testing device provided in an embodiment of this disclosure is shown; as follows: Figures 1-2 As shown, the display cover 1 includes an upper cover plate, a lower cover plate, a left cover plate, and a right cover plate. The upper cover plate, lower cover plate, left cover plate, and right cover plate are assembled to form a rectangular mounting opening. The display panel 2 can be inserted into the rectangular mounting opening. The display panel 2 is used to mount vehicle components and an independent / integrated debugging mode switching button. The vehicle components include: a battery management component, a motor control component, a vehicle control component, and a brake management component. An outward-opening cover door is provided on the opposite side of the rectangular mounting opening, which allows for quick and convenient replacement / repair of the relevant components mounted on the display panel 2. The inner surface of the cover door is provided with reinforcing ribs to meet the strength requirements during actual use. Furthermore, a heat dissipation component is also provided in the upper cover plate, and the heat dissipation vent of the heat dissipation component is located on the upper surface of the upper cover plate. At least one side of the left cover plate and the right cover plate is provided with an integrated debugging wiring port.

[0036] Furthermore, the display cover 1 is fixedly installed on the rear beam 31 of the platform 3. The rear beam 31 is provided with wiring holes to facilitate the wiring of the components mounted on the display panel 2 when making electrical connections. A cover plate is provided above the front beam 32 of the platform 3 to form a carrying plate. The lower surface of the platform 3 is provided with a left main frame 4 and a right main frame 5, and the platform 3 is mounted on the left main frame 4 and the right main frame 5. At least one of the main frame cavities is provided with a side drawer, which can be used to store test accessories, calibration tools and other devices, avoiding the occupation of operating space by scattered items. In addition, the lower surface of the platform 3 is evenly distributed with reinforcing ribs to enhance the load-bearing capacity.

[0037] Furthermore, corresponding guide rails are provided on the opposite sides of the left main frame 4 and the right main frame 5, which can be used to install pull-out plates. Test accessories, calibration tools, etc. can be placed on the pull-out plates. A foot pedal is provided between the lower main plates of the left main frame 4 and the right main frame 5, and a braking device 6 is installed on the foot pedal. In addition, decorative panels for beautifying the appearance of the equipment are provided on the outer sides of the left main frame 4 and the right main frame 5. Light strips are installed in the decorative panels, and the light strips are lit when the equipment is running normally.

[0038] It is understandable that vehicle components can be integrated and tested via connecting cables, meaning that multiple devices equipped with different components can be integrated and tested via connecting cables.

[0039] In addition, such as Figures 1-2 As shown, the left main frame 4 and the right main frame 5 can also have cable routing holes opened as needed to install hubs / racks.

[0040] In this embodiment, the display cover 1 is welded together with the cover plates, the display cover 1 is welded together with the platform 3 as a whole, and the platform 3 is welded together with the left main frame 4 and the right main frame 5.

[0041] Figure 3 An example diagram of a battery management component provided in an embodiment of this disclosure is shown; as follows: Figure 3 As shown,

[0042] The display panel 2, equipped with a battery management component, is housed within the display cover 1. The upper cover of the display cover 1 contains a cooling fan, and the left cover has a connection interface. The display cover 1 is welded to the platform 3, which is mounted on the left main frame 4 and the right main frame 5 and welded to both main frames. Guide rails with pull-out plates are located on opposite sides of the two main frames near the platform 3. A foot pedal with a braking component 6 is located on opposite sides of the two main frames near the ground. The battery management component mounted on the display panel 2 is electrically connected to the braking component 6. Additionally, decorative panels with LED strips are located on the outer sides of the two main frames, and a side drawer is located in the cavity of the right main frame 5. The battery management component includes: a system power supply, a thermal management simulation module, a battery pack, a battery management system, a high-voltage junction box module, an AC charging port, a mode conversion button, a switching power supply, and a load simulation module. Furthermore, the display panel 2 also includes an industrial display.

[0043] Furthermore, the system power supply can be a 12V switching power supply; the battery management system includes a main control board and a data acquisition board; the thermal management simulation module can simulate battery temperature changes by adjusting a knob to verify the thermal management function. When the battery temperature is higher than the set value, the main control board issues a heat dissipation command, closes the heat dissipation relay, and the cooling fan starts working until the temperature drops to the normal range; when the battery temperature is lower than the set value, the main control board issues a heating command, closes the heating relay, and the heating resistor starts working until the temperature rises to the normal range; the load simulation module can simulate load conditions in independent mode, adjust the load, and observe changes in battery status; the high-voltage junction box module also... This is called a high-voltage distribution box. It's a device that distributes the electrical energy delivered by the power battery pack to the motor controller, air conditioner compressor, and PTC heater. In addition, during AC slow charging, the charging current also flows into the power battery through the junction box to charge it. The junction box has a fuse for each of the electric compressor circuit, PTC heater circuit, and AC slow charging circuit. When the current in the above circuits exceeds a certain value, the fuse will blow within a certain time (the higher the current, the faster it blows), protecting the relevant circuits. The AC charging port can convert AC power to DC power. The mode switching button can be used to switch between independent mode and joint debugging mode. The switching power supply is the emergency stop and start switch for the equipment.

[0044] In this embodiment, a host computer and development software can also be used to communicate with other components via the CAN bus to control the entire system and perform data acquisition and analysis.

[0045] It is understandable that devices equipped with battery management components can be used in conjunction with devices equipped with vehicle control components, motor control components, and braking energy management components. When used in conjunction, simply connect the connection cable and press the mode switch.

[0046] Figure 4 An example diagram of a motor control assembly provided in an embodiment of this disclosure is shown; as follows: Figure 4 As shown, the display panel 2, which carries the motor control components, is fitted into the display cover 1. The upper cover of the display cover 1 has a built-in cooling fan, and the left cover has a connection interface. The display cover 1 is welded to the platform 3, which is mounted on the left main frame 4 and the right main frame 5 and welded to the two main frames. Guide rails are provided on opposite sides of the two main frames near the platform 3, and pull-out plates are provided in the guide rails. Steps are provided on opposite sides of the two main frames near the ground. In addition, decorative panels with light strips are provided on the outer sides of the two main frames, and a side drawer is provided in the cavity of the right main frame 5. The motor control components include: a main control computer, the motor under test, a coupling and torque sensor, a dynamometer motor and its driver, a resolver sensor and its acquisition module, a control unit, and an open-source micro motor driver, as well as a mode switching button. In addition, the display panel 2 is also equipped with dual industrial displays.

[0047] Furthermore, the main control computer is equipped with a host computer and development software, communicating with other parts via two CAN buses, and is responsible for overall control, data acquisition, and analysis. The resolver acquisition module can collect information from the loading motor, converting the sine and cosine analog signals of the resolver into angle digital signals, which are output in parallel port mode, while simultaneously outputting the phase signals of the incremental encoder. The dynamometer motor is controlled by a frequency converter. When the frequency converter receives the dynamometer enable signal sent by the loader via the 485 bus, it controls the dynamometer motor to rotate at the set speed. The motor under test is controlled by an open-source micro motor driver. After receiving the motor enable signal sent by the main control computer via the CAN bus, the driver will determine the initial position of the motor under test. If the initial position cannot be determined... The tested motor does not respond to rotation commands; its initial position is determined by the rotation of the dynamometer motor via a coupling. After rotation, the tested motor transmits its information to the main control computer via the CAN bus for data analysis. The torque sensor collects torque and speed information from both motors and transmits it to the loader via the 485 bus. The loader then transmits the data to the main control computer via the CAN bus for analysis. The loader itself can also directly display the real-time torque and speed of the motor. The control unit and open-source micro-motor driver control the tested motor's rotation after receiving the motor enable signal from the main control computer and collect the tested motor's information, transmitting it to the industrial control computer via the CAN bus for data analysis. The mode switch button can be used to switch between independent mode and joint debugging mode.

[0048] It is understandable that the main control computer can control the driver of the motor under test and the vehicle model loader through two CAN buses respectively, so as to achieve the purpose of controlling the motor under test and the loading motor. The information collected by the torque sensor and the frequency converter is first transmitted to the vehicle model loader through the 485 bus, and then transmitted to the main control computer through CAN communication. The coupling between the motor under test and the dynamometer motor can realize the synchronous control between the motors.

[0049] In this embodiment, the dynamometer motor, dynamometer motor driver, torque sensor, etc. form a functional test unit; the open-source micro motor driver is divided into a control circuit board and an isolation drive circuit board, which can be programmed and tested with different engineering codes as needed.

In addition, the display panel 2 also carries an industrial display.

[0051] Furthermore, the main control computer is equipped with a host computer and development software, and communicates with other parts via the CAN bus, responsible for overall control, data acquisition, and analysis; the brake / accelerator signal acquisition module can acquire brake and accelerator signals in real time and transmit them to the VCU vehicle controller via the CAN bus; the gear switch and gear signal acquisition module can perform gear shifting and provide feedback on the current gear information; the brake energy recovery module can switch the brake energy recovery level via a level switching knob; the instrument cluster module uses analog mechanical dials, digital and graphical methods to display the vehicle's digital quantities, integrates vehicle status, vehicle control, and fault detection functions, and has vehicle function indicator icons, which can indicate the execution of the corresponding function when the icon is lit; the vehicle controller module is responsible for processing the acquired signal information, and then connects the instrument cluster and the main control computer via CAN communication for overall vehicle control; the mode switching button can be used to switch between independent mode and joint debugging mode.

[0052] In this embodiment, the corresponding data acquisition module can collect acceleration signals, braking signals, throttle signals, gear signals, etc., and transmit them to the vehicle controller - VCU via CAN communication. After the VCU processes the collected data, it transmits it to the main control computer and the instrument cluster via CAN communication.

[0053] In addition, such as Figure 5 As shown, the device can also be optionally equipped with casters for easy movement.

The upper cover of the display cover 1 has a built-in cooling fan, and the left cover has a connection interface. The display cover 1 is welded to the platform 3, which is mounted on the left main frame 4 and the right main frame 5 and welded to both main frames.

A motor and its controller, a mechanical braking device, a moment of inertia device, etc. can be added. In addition, the display panel 2 is also equipped with dual industrial displays.

[0055] Furthermore, the host computer communicates with other components via the CAN bus, and the vehicle controller is responsible for overall control; the signal acquisition module collects brake / accelerator pedal signals and feeds them back to the vehicle controller via the bus; the electronic control unit includes a one-button start button, a power button, and an emergency stop switch to control the on / off operation of the equipment; the mode switching button can be used to switch between independent mode and integrated debugging mode; if a motor and its controller, mechanical braking device, and rotational inertia device are added, the motor's operating mode can be dynamically adjusted to simulate braking energy recovery efficiency tests under different load conditions; the industrial display shows parameters such as braking energy recovery rate and battery charging current in the form of data charts, supports curve trend analysis, and can also display equipment operating status, fault codes, and operation prompts in real time.
